____ [38]3 years ago
5 0
When we have power function or exponential, or then we have a/x, then functions are not going to give arithmetic sequence, because an arithmetic sequence it is really a linear function  when x are natural numbers,

so we need to check  only A
<span>f(x)=- x/3 +5
 
x  1             2               3              4              5
y 14/3      13/3         12/3        11/3        10/3           arithmetic difference is -1/3

so the answer is A</span>

worty [1.4K]

Answer:

3.7%

Step-by-step explanation:

We know that from this situation, the probability of drawing a single green marble is 1/3. However, to find the probability of drawing 3 green marbles, we will need to do:

P= \frac{1}{3}* \frac{1}{3}*\frac{1}{3}

We get a probability of:

P= \frac{1}{27}

This converts to a percentage of:

\frac{1}{27}= 0.037 \\ 0.037*100= 3.7%

We get a percentage of 3.7%
